The best-selling steamy sensation 'Fifty Shades Of Grey' has been voted Book of the Year by the public.

The novel, by EL James, is the first of a trilogy of saucy tales dubbed "mummy porn". It fast became a literary phenomenon, selling more than six million copies to become the best-selling book of all time in the UK.

It won more than three quarters of the votes after the public were asked to cast a ballot for their favourite read as part of this year's Specsavers National Book Awards.
